Just a heads up that Minnesota State Patrol is giving tickets for speeds higher than what the driver is actually traveling. I got a warning for going 66 in a 55 while watching my speedometer carefully – it said 64. A few months later, in a different part of the state, I got a ticket for going 80 in a 70 while watching my speedometer carefully – it said 78. After both incidents, I timed my speed with a new GPS that is accurate to 1/10th of a mph. My speedometer reads between -0.5 to +1 mph of the true speed I am going. Therefore, I could easily have been going 65 and 79, respectively, but the officers’ radar guns clearly are calibrated at least +1 mph from the true speed. This is unethical and probably illegal! Spread the word.
